Como enlazar jquery ??

[Pablo Ayala]

Estas llamando 2 veces a jquery....

Solo debes hacerlo una vez:

Código HTML:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
    <script src="../../jquery.flexslider-min.js"></script>
        <script src="../../jquery.colorbox.js"  ></script>
        
    <script type="text/javascript">
        $(window).load(function() {
            $('.flexslider').flexslider();
        });
 
        $(document).ready(function(){
            //Examples of how to assign the ColorBox event to elements
            $(".group1").colorbox({rel:'group1'});
            $(".group2").colorbox({rel:'group2', transition:"fade"});
            $(".group3").colorbox({rel:'group3', transition:"none", width:"75%", height:"75%"});
            $(".group4").colorbox({rel:'group4', slideshow:true});
            $(".ajax").colorbox();
            $(".youtube").colorbox({iframe:true, innerWidth:853, innerHeight:480});
            $(".iframe").colorbox({iframe:true, width:"80%", height:"80%"});
            $(".inline").colorbox({inline:true, width:"50%"});
            $(".callbacks").colorbox({
                onOpen:function(){ alert('onOpen: colorbox is about to open'); },
                onLoad:function(){ alert('onLoad: colorbox has started to load the targeted content'); },
                onComplete:function(){ alert('onComplete: colorbox has displayed the loaded content'); },
                onCleanup:function(){ alert('onCleanup: colorbox has begun the close process'); },
                onClosed:function(){ alert('onClosed: colorbox has completely closed'); }
            });
            
            //Example of preserving a JavaScript event for inline calls.
            $("#click").click(function(){ 
                $('#click').css({"background-color":"#f00", "color":"#fff", "cursor":"inherit"}).text("Open this window again and this message will still be here.");
                return false;
            });
        });
    </script>
 

Saludos!
